Wächter Packautomatik GmbH & Co. KG des
Lenze - Tablomat ST.jpgigns and manufactures custom automated packaging systems. Incorporating a tailor-made automation solution from Lenze America Corp. Wächter Packautomatik replaced a multi-vendor automation system with its own system. thereby reducing engineering, commissioning and maintenance costs.
A specialist in ultra-modern packaging technology, Wächter was also able to realize new functions that improve the performance of the machines and cut down on automation components.
Working in close collaboration with Lenze, Wächter Packautomatik managed to increase the flow rate, shorten commissioning times and cut costs. This was extremely beneficial to Wächter's customer, a leading German discounter, which designed a ship-to-store shelf corrugated cardboard (décolleté) tray and needed a machine that could pack it.
To make these trays, Wächter modified its Tablomat ST machinery and added a Tablomat D tray erector. The resulting machine folds and glues carton pieces to form the complete package, including the cover clip. The carton components are removed from a feeding magazine using a vacuum suction cup, separated, deposited and transported by conveyor belt to the first processing step.
Comprehensive range of coordinated automation products
At the heart of this new packaging system are the Lenze components: 9400 HighLine, MCS gearmotor, I/O 1000 and the EL-100 HMI. The 9400 HighLine, with integrated safety, is used for the tray withdrawal, inserter and time stamp, eliminating the need for a separate PLC. The drive-based architecture works with an electronic cam group and a master axis. Synchronizing the master and slave axes, the 9400 servos communicate with each other via a CAN bus and with the logic components via a second CAN bus. It's fast, flexible and cost efficient.
Stefan Wächter, Wächter Managing Partner says, "We shortened commissioning times by at least 25 percent and considerably simplified machine maintenance in the new Tablomat D. This was a crucial element in increasing the number of machine cycles from 25 to 30."
Wächter adds, "The training courses and tailored engineering serv

The comprehensive range of coordinated automation products is one of the main reasons why Wächter chose Lenze. Wächter says, "We have used Lenze gearmotors in previous packaging machines because of their durability and response. Being able to employ their servo drives and controls in this new machine was the natural next step. Plus the software Lenze designed for us is so modular, we can readily create new variations of the machine as future demands require."
